Colorism is discrimination based on skin tone. Skin color influences clinicians’ diagnostic impressions. The degree to which colorism influences counseling students’ clinical decision making is unknown. This study examined colorism's effect on counselor education master's students’ (N = 154) clinical decisions. Analysis of covariance failed to produce statistically significant results when comparing students’ evaluations of a male African American's mental health and wellness, when controlling for presentation management, across 4 skin tones. Counselors should include colorism in diversity training. El colorismo es la discriminación basada en el tono de la piel. El tono de la piel influye en las impresiones diagnósticas de los profesionales clínicos. Se desconoce hasta qué punto el colorismo influye en las decisiones clínicas de los estudiantes de consejería. Este estudio examinó el efecto del colorismo en las decisiones clínicas de estudiantes de maestría en educación de consejeros (N = 154). El análisis de la covarianza no produjo resultados estadísticamente significativos al comparar las evaluaciones de los estudiantes sobre la salud mental y el bienestar de un cliente afroamericano varón, controlando la gestión de la presentación de 4 tonos de piel diferentes. Los consejeros deberían incluir el colorismo en la capacitación de diversidad. 相似文献

High-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) with Z-contrast is applied to characterize the antiphase boundary (APB) of the B2 structure in a rapidly solidified TiPd melt-spun compound. The atomic shift associated with the R ?=?(1/2) a 0 ?111? type displacement vector is directly observed at the boundary. A microstructure modification of the melt-spun compound with the cooling rate during solidification is also described. 相似文献

The present research investigated the justifications for bullying as a function of the various roles that children assume in bullying. Contrary to expectations, most children judged bullying to be right or at least permitted regardless of their role in the episode. However, children with different types of involvement in bullying showed different justification strategies. In particular, bullies were more likely to blame the victims than were children assuming other roles. Gender differences were found in the justifications provided. Boys were more likely to blame the victims, whereas girls were more likely to engage in denial of injury. These results support the notion that justifications for bullying function to sustain bullying. 相似文献

Greater support is required in health promotion for practitioners to adopt critical approaches to their practice. Despite recognition of the role that critical reflection can play in supporting critical practice, it is underdeveloped in health promotion. This pilot study aimed to explore the use of critical reflection with health promotion practitioners. Critical postmodernism provided the theoretical perspective and critical reflection methodology guided the study. The data collection method involved the application of a critical reflection model via in-depth semi-structured interviews with two health promotion practitioners who were recruited using purposive sampling. Critical postmodernism and critical health promotion values and principles were the thematic frameworks used to analyse the data. Four types of assumptions were identified across both participants’ narratives: binary opposites and dichotomous thinking; identity and othering; professionalism; and power. Two key themes that evidenced these assumptions were conceptualising power as a commodity, and identity in the Aboriginal and Torres Strait Islander context. Both traditional and critical health promotion practice approaches were evident in participants’ practice. The process of engaging in critical reflection resulted in positive outcomes for the practitioners, including the identification of new, more critical ways of practising. Critical reflection provides a process for developing critical health promotion practice. The designation of critical reflection as a core health promotion competency may enhance the development of critical health promotion. Further research is needed to develop and test a critical reflection model incorporating the values and principles of health promotion with a larger sample of practitioners. 相似文献

A broadly used computational framework posits that two learning systems operate in parallel during the learning of choice preferences—namely, the model-free and model-based reinforcement-learning systems. In this study, we examined another possibility, through which model-free learning is the basic system and model-based information is its modulator. Accordingly, we proposed several modified versions of a temporal-difference learning model to explain the choice-learning process. Using the two-stage decision task developed by Daw, Gershman, Seymour, Dayan, and Dolan (2011), we compared their original computational model, which assumes a parallel learning process, and our proposed models, which assume a sequential learning process. Choice data from 23 participants showed a better fit with the proposed models. More specifically, the proposed eligibility adjustment model, which assumes that the environmental model can weight the degree of the eligibility trace, can explain choices better under both model-free and model-based controls and has a simpler computational algorithm than the original model. In addition, the forgetting learning model and its variation, which assume changes in the values of unchosen actions, substantially improved the fits to the data. Overall, we show that a hybrid computational model best fits the data. The parameters used in this model succeed in capturing individual tendencies with respect to both model use in learning and exploration behavior. This computational model provides novel insights into learning with interacting model-free and model-based components. 相似文献

The kynurenine (KYN) pathway, which is initiated by indoleamine 2,3-dioxygenase, is the main tryptophan (TRP) metabolic pathway. It shares TRP with the serotonin (5-HT) pathway. We investigated the influence of inescapable-predator (rat) stress on behavior and brain TRP metabolism in mice. Male ICR mice (4W) were exposed to 20-min inescapable-predator stress. Behavior on an elevated plus-maze, and TRP, KYN, and 5-HT levels in the prefrontal cortex, hippocampus, amygdala, and dorsal raphe nuclei were measured 1 and 4 weeks after stress exposure. Predator stress increased the number of open-arm entries (NOA) 4 weeks after stress exposure without altering the number of closed-arm entries (NCA). Thus, the open/closed-arm entry ratio (NOA/NCA) increased after stress exposure. Predator stress increased KYN levels in the prefrontal cortex (until 4 weeks after stress exposure) and dorsal raphe nuclei (for 1 week after stress exposure), decreased 5-HT levels in all brain regions (until 4 weeks after stress exposure). Thus, predator stress increased the KYN/5-HT ratio in all regions, in particular in the prefrontal cortex and hippocampus until 4 weeks after stress exposure. Predator stress shifted the balance between the KYN and 5-HT pathways to the KYN pathway, and induced behavioral disinhibition. 相似文献

This study examined neural features of emotional responses to errors. We specifically examined whether directed emotion regulation
of negative emotion associated with error modulates action-monitoring functions of anterior cingulate cortex, including conflict
monitoring, error processing, and error prevention. Seventeen healthy adults performed a continuous performance task during
assessment by fMRI. In each block, participants were asked either to increase or decrease their negative emotional responses
or to react naturally after error commission. Emotion regulation instructions were associated with modulation of rostral and
dorsal anterior activity and of their effective connectivity following errors and conflict. Cingulate activity and connectivity
predicted subsequent errors. These data may suggest that responses to errors are affected by emotion and that aspects of emotion
and cognition are inextricably linked, even during a nominally cognitive task. 相似文献

A comparison of the mechanical effect of arm swing and countermovement on the lower extremities in vertical jumping 总被引:1,自引:0,他引:1
The purposes of this study were to quantify and compare how arm swing and countermovement affect lower extremity torque and work during vertical jumping and to gain insight into the mechanisms that enable the arm swing and countermovement to increase jump height. Five participants maximally performed two types of vertical squat jumps with (SJA) and without (SJ) an arm swing and two types of countermovement vertical jumps with (CJA) and without (CJ) an arm swing. The participants jumped from a force platform and all performances were videotaped with a high-speed video camera (200Hz). Jump heights, joint torques and work were calculated by combining kinematic and kinetic data. It was found that of the four jumping conditions, the participants jumped highest when they used an arm swing with countermovement (i.e., CJA). The increase of the countermovement jump height with an arm swing is the result of the increase of the lower extremity work. In the hip joint, the increase in torque caused by the countermovement predominantly occurred at the beginning of the propulsion phase, while the increase in torque caused by the arm swing occurred in the rest of the propulsion phase. A key finding of our study is that arm swing and countermovement have independent effects on lower extremity work, and their effects are additive in CJA to produce greater jump height. 相似文献

Research Ethics Boards (REBs) provide oversight for Canadians that research projects will comply with standards of ethics if the studies are carried out as described in the documents that have been approved. While REBs have traditionally been affiliated with institutions such as universities and hospitals, a number of factors - including the increased volume of research being conducted outside academic centres - have resulted in the establishment of some private or independent REBs. This, in turn, has raised concerns about the credibility of REBs in the private sector and their capacity to handle issues around conflict of interest. This Breakout Session was an opportunity to hear the perspectives of people associated with institutional and private REBs and examine perceived problems with boards in the private sector, scrutinize theoretical and structural differences between types of REBs, and look at whether or not there is room for both institutional and private boards in the Canadian research review landscape. 相似文献
